This new paper discovered that many clinical trials involving homeopathy have not been registered, the principle final result was modified in 1 / 4 of these which have been revealed, and most of the trials stay unpublished.

He and his staff sought to be taught if the revealed clinical trials won’t signify all of the scientific research on homeopathy, however a choose few reporting solely optimistic outcomes. That is what’s meant by reporting bias.
